RV-C Network Connectivity

The Reporter was designed to interface with the coach-side 

RV-C network to aid in the Aqua-Hot’s integration into the on-

board RV-C network.

There is an indicator light on the back of the Reporter which 

shows the current status of the Reporter’s connection to the 

RV-C network. This will be useful when diagnosing potential 

problems with the coach-side RV-C network.

This mode can accessed under the test page of the Aqua-Hot 

Reporter (see below).

Once the test page is open, select the MANUAL MODE and 

select “NEXT”. Manual mode will continue to run for up to 3 

days without any user intervention. Pressing the reset button 

at any time while enabled will reset the timer, and run for an 

additional 3 days.

All heating zones are linked together and can be run at 25%, 

50%, 75%, and 100% (as shown below). The burner and electric 

can be enabled or disabled. For all levels, there is a 10 minute 

duty cycle period that will allow Cozy fans to be on for the 

specified percentage of 10 minutes. Example, 25% would be on 

for 2.5 minutes, and then off for 7.5 minutes. It always starts 

with the on-cycle, then shuts off for the remainder of the 10 

minute period.

If the system power is cycled, the manual mode will be disabled 

and must be manually reactivated. Leaving the manual mode 

page will also disable manual mode and restore normal 

operation. Leaving manual mode should be done once the 

system failure has been resolved and normal operation can 

resume. 

NOTE: 

If using the rocker switches, burner & electric switches 

must be toggled on/off after leaving Manual Mode.

Manual Mode

The 2.0 Reporters with CFG 1.9 and greater come with a manual 

mode in case the general coach RV-C network fails. It will allow 

for limited operation while the larger network/module problem 

is addressed.
To determine the version of Reporter, the Reporter 2.0 modules 

are shipped with version decals affixed to the back of the circuit 

board, OR shown on the home screen - “FW: 2.0”.
